March 30, 2007 -- In a surprise move, a FDA advisory committee yesterday recommended approval of the cancer immunotherapy Provenge from Dendreon. The drug treats prostate cancer, but it missed its endpoint in a Phase III trial, which was to extend the time-to-progression in prostate cancer patients whose disease did not respond to hormone therapy. A subsequent analysis showed that the drug extended median survival by 4.5 months, raising it to 25.9 months from 21.4 months.
